HEADLIGHT.

Specification of Letters Eatent.

?atented May 28, 1918..

Application filed September 14, 1917. Serial No. 191,404.

To all whom it may concern:

Be it known that we, TRUMAN W. Posr and CLARENCE B. DesJARDINS,CltlZBIlS 0f the United States, residing at Providence andToledo, in the counties of Providence and Lucas and States of RhodeIsland *nd Ohio, respectively, have invented certain new and usefulImprovements in Headlights, of which we declare the following to be afull, clear, and exact description.

This invention relates to improvements in headlights and moreparticularly to headlights which are provided with a pivotally mountedreflector which may be tilted to throw the beam of light downwardly uponthe ground when approaching another vehicle or a pedestrian so as toavoid the objectionable glare,

The principal object of our invention is to provide a simple andellicient means for stiflening and reinforcing the front edge of thereflector and at the same time providing the pivotal mounting for thereflector.

A further object of our invention is to provide simple and eflicientmeanswhich will afford a pivotal mounting for the re flector and will,at the same time, stiffen the front edge of the reflector and retain atransparent covering over the front of the reflector so'as to preventmoisture gaining access to the reflecting surface, so as to tarnish thesame.

Further objects, and objects relating to economies of manufacture anddetails of construction, will definitely appear from the detaileddescription to follow.

We accomplish the objects of our inven tion by the devices and meansdescribed in the following specifications. Our invention is clearlydefined and pointed out in the appended claims.

A structure constituting a preferred em bodiment of our invention isillustrated in the accompanying drawings, forming apart of thisspecification, in which:

Figure I is a vertical, sectional View, through a headlight embodyingour invention.

Fig ll is a transverse, vertical, sectional morals refer to similarparts throughout the Y several views, and the sectional views are takenlooking in the direction of the little arrows at the ends of the sectionlines.

Considering the numbered parts of the drawing, we have shown a headlightembodying a casing 10, the front of which is closed by lens 11 carriedby a ring 12 in the usual manner. A reflector 13 is pivotally mountedwithin the casing 10 and carries a socket 14, which receives theelectric light bulb 15, said socket being connected by the wires 16 withthe connector 17 carried by the rear of the casing 10. An annularchannel 19 which faces ,forwardly is formed in the forward edge of thereflector 13 and a packing ring 20 of wicking or other suitable materialis disposed in said chanml.

Said packing ring may be held in place by shellac if desired. 'Beyondthe channel 1?? the material from which the reflector is formed is bentforwardly and then rearwardly around a pair of semi-circular reinforcingwires 21, which, together, form a continuous annular reinforcing bead,serving to preserve the true parabolic shape of the reflector since thefree edge of the re flector will always be maintained circular. Openingsare provided in the bead 22 at diametrically opposite points and theopposite ends of said reinforcing wires are bent laterally at 26 andextend through said 0 enin s formi the trunnions for the P g Hreflector. The reflector is closed by the transparent pane of glass 18which rests against the bead 22 and the packingtring 20, as clearlyshown in Figs. I and 1V, and

this of glass is retained in place the split channel-shaped clampingring 23 which embraces the bond 22 and the periphcry or the pane l8 andis provided with a pair of radially extending cars 24, through which abolt 25 passes to draw the parts of the ring together. The ring 23 isprovided with diametrically opposite openings through which trunnions 26extend. Spring strips 27, which are arched somewhat, are secured attheir ends to the casing 10 by the rivets 28 and carry bearin blocks 29in which the trunnions 2c of too reflector are journaled. Thisconstruction aflords. a spring bearing for the reflector trunnions. A.clamp 30 embraces the socket I l between the reflector 13 and the casing10 and is connected to a wire 31 which passes out, through a tube 32carried in a boss 33 secured to the casing 10, the tube 32 being heldagainst movement by the set screw 84:. Thewire 31 may be meni ulated inany suitable manner to tilt the re rector on its trunnions.

From the description of the parts given above, tee operation of thisdevice shou d be very reedil understood. It will be seen that thereinforcing wires 21 which form the reinforcing bead to stiffen thefront edge of the reflector so as to ireep it in shape, are extended toform the trunnions for the reflector. This makes a very simpleconstruction and one which can be produced very cheaply. it will be seenthat in this construction the reflector trunnions are carried by thereflector itself and not by the clamping ring which secures the pane ofglass 18 to the front of the reflector. The reflector may be formedtogether with the trunnions, after which the pane of glass may be anplied to the front of the reflector and se cured in place by theclamping ring 23 and the whole reflector then be mounted in itsbearings, The beering blocks 29 are spring-mounted and will yieldsufliciently to permit the insertion of the trunnions.

lve have shown a simple means for manipulating the reflector so as totilt it upon its ours, but this tilting mechanism forms no part of ourinvention, which has to do with the construction of the reflectorrrunnions, the stiflening for the front edge oi the reflector, means forsecuring the trains parent covering for the reflector in niece and thspring trunnion bearings.

l-v'c are aware that the particular embodiment of our invention, whichwe have here shown, is susceptible of considerable variation withoutdeparting from the spirit thereoi, and, therefore, we desire to claimour invention Broadly, as well as specifically, as indicated by'theappended claims.
